Geospatial Functions

coordinate_converter(vdf, x, y[, x0, ...])

Converts between geographic coordinates (latitude and longitude) and Euclidean coordinates (x,y).

intersect(vdf, index, gid[, g, x, y])

Spatially intersects a point or points with a set of polygons.

split_polygon_n(p[, nbins])

Splits a polygon into (nbins 2) smaller polygons of approximately equal total area.

Index Functions

create_index(vdf, gid, g, index[, ...])

Creates a spatial index on a set of polygons to speed up spatial intersection with a set of points.

describe_index([name, list_polygons])

Retrieves information about an index that contains a set of polygons.

rename_index(source, dest[, overwrite])

Renames a spatial index.

Import/Export

read_shp(path[, schema, table_name])

vDataFrame.func(...)

to_geopandas(geometry)

to_shp(name, path[, usecols, overwrite, shape])

Creates a SHP file of the current vDataFrame relation.

Plotting & Graohics

vDataFrame[].func(...)

geo_plot(*args, **kwargs)
